Abstract

The invention relates to a method for controlling the communication security of an unmanned aerial vehicle assisted cognitive wireless network. The method comprises the following steps: step S201, establishing a communication model of unmanned aerial vehicle-to-ground wireless communication; step S203, determining each parameter in the communication model; s205, establishing a non-convex optimization problem model according to each parameter in the communication model; s207, converting the non-convex optimization problem model into a convex optimization problem model by using a slack variableand a continuous convex approximation method; and S209, according to the convex optimization problem model, determining the target flight path and the target transmitting power of the unmanned aerialvehicle and the average secrecy rate of the secondary user receiving end under the worst condition. According to the method, the average secrecy rate of the secondary user receiving end under the worst condition is maximized by jointly optimizing the flight path and the transmitting power of the unmanned aerial vehicle within the given flight time, so that safe transmission of information is effectively guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a control method for UAV-assisted cognition of wireless network communication security. Background technique [0002] In recent years, with the development of technology and the reduction of costs, the market demand for drones has continued to grow, and the application fields have continued to expand. UAV-assisted communication has gradually become a research hotspot in the field of wireless communication. Compared with traditional ground communication systems, the main advantages of air-ground communication systems using UAVs are: rapid deployment, low operating costs, on-demand, and good line-of-sight transmission performance. However, due to its natural openness and broadcast characteristics, wireless communication is extremely vulnerable to malicious eavesdropping by illegal users. How to ensure the security of UAV communication system is a b...
